Now have days where I have no BOWEL control at all,comes without warning! I barely eat,appetite decreased. Mouth ALWAYS dry,have chills,and hot flashes! I like the weight loss, however the bowel problems are un-predictable and over-whelming especially when I am teaching! Is this overdose reaction,or should I talk to my NP and wean off completely and go back to Effexor or other? Thank-you!
